Polymer Char Author Profile


Alberto Ortín

Senior Scientist at Polymer Char

 

Dr. Alberto Ortín received a Master’s Degree in Electronics Engineering at the Polytechnic University of Valencia, Spain, and a Master’s Degree in Analytical Chemistry from the University of Valencia. He received his Ph.D. in Chemistry from the same University of Valencia in 2014.

He is now a Senior Scientist at Polymer Char, where he has accumulated over 25 years of experience in the development of instruments, software, and detectors for different polyolefin characterization techniques, including GPC, TREF, and cross-fractionation. He has authored several papers on polyolefin separation methods at high temperature and is a major contributor to the technical program of the International Conference on Polyolefin Characterization.
